Mood Tracker · MoodQuad

Your mood is more predictable than you think.

MoodQuad is a daily mood tracker that reads your biometric data from Apple Health - heart rate variability (HRV), resting heart rate, respiratory rate, sleep, and workouts - and builds a personalized emotional forecast based on your patterns.

One tap per day. That's your only job. MoodQuad does the rest.

THE MOOD FORECAST

After 2 weeks of daily check-ins, MoodQuad predicts how you'll feel tomorrow based on how your body actually performed overnight. Not a generic wellness score. Your data. Your patterns. Your forecast.

Works with Apple Watch and Whoop via Apple Health. Choose your preferred data source in Settings.

HOW IT WORKS
